IMPROVEMENT IN MACHINESv FOR CROZING AND CHAMFERING STAVES.

Specification forming part of Letters Patent No. 205,544, dated July 2,1878; application filed December 5, 1577.

To I'll whom it may concern:

Be it known that we, GEO. \V. GRODHAUS and GEO. O. GnonHAUs, ofBellaire, in the county of Belmont and State of Ohio, have inventedcertain new and useful Improvements in Machines for Making Barrels,Keg-s, and other Coopered Ware; and we do hereby declare that thefollowing is a full, clear. and exact description thereof, that willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

The same letters and figures of reference are used to indicate thecorresponding parts.

After describing the invention, its nature and extent will be shown inthe claims.

The object of our invention is to provide an improved machine forbeveling, chamfering, and crozing barrels or kegs of any description,saving both time and labor, and producing a superior article ofmanufacture.

Our invention consists of an elevated platform, provided with twoupright posts. To the top of one of said posts thereis pivoted a lever.One end of said lever rests on the top of the other post, which isslightly shorter than the one first named. From this lever is suspendeda disk, whose hollow frame-work receives the top of the barrel or keg.To the platform on which these uprights rest is attached a shaft, havingbearings in the sides of the platform. This shaft is operated by a crankat one end of it, with a shoe attached to said crank. A bevel-wheelattached to this shaft engages with another bevel-wheel attached to ashaft placed at right angles, or in a vertical position, to thefirst-named shaft. To the vertical shaft is attached the tool-box, whichcontains the instruments for evening, beveling, and crozing the lowerend of the barrel. To this shaft also is attached the framework of asecond disk, the counterpart of the firstnamed disk, for receiving thelower end of the barrel.

But a more detailed description will appear farther on.

Figure l is a side view of my invention. Fig. 2 is a top view. Fig. 3 isa perspective View of the tool-box. Fig. 4 is a view of the hammer whichI use for driving the hoops on the barrel. Fig. 5 is an enlarged view ofthe clamp to which one end of the top lever is attached before thebarrel is placed within the disks.

A A are two upright posts which rise from the platform B. G is a lever,one end of which is pivoted to the post A, the other end of which restson the post A when the machine is in operation. A similar lever, withits suspended disk of hollow frame-work, is also hinged against thewall, back of the work-bench, and at the proper height from it, so thatit may be used to force, down the head truss-hoop of the barrel or kegwithout the. aid of a hammer.

The disk D is suspended from the lever G, and receives and holds thebarrel in position while it is beingfinished, and presses it against thetools in the tool-box.

In suitable bearings on the sides of the platform B is journaled theshaft E, to one end of which is attached the shoe F. The shoe F isweighted by its lower part being made of cast-iron and its upper part ofwood. This is done that it may be more easily controlled by the foot.

The beveled cog-wheel K is rigidly attached to the shaft E. With thewheel K the beveled cog-wheel L engages. The wheel L is rigidly attachedto the upright shaft M, which has a bearing in the platform B. Theupright shaft M is kept in position by the supporting-braces H H, uponwhich is the platform H, which it pierces at the top. The driving-wheelG is rigidly attached to the sh aft M. The elevated platform H rests onthe supporting-braces H H.

N N are steel springs, which rest on the elevated platform H and oneither side of the shaft M. The disk D and its depending frame-work isjournaled to the shaft M, and rests on the springs N N. To the shaft Mis fastened the tool-box I. The top of the tool.- box I is open, exceptthe bridges g g, which are needed to hold the tools in position. In thetool-box I are the movable tools a, b, c, and d, used for evening,beveling, chamfering, and crozin g the end of the barrel. These toolsare kept rigid by two set-screws in the side of the tool box. Thecroze-holder, containing the croze-cutter c, is provided with the springf on its upper part, as shown in Fig. 3.

When the croze-cutter c is needed for use it is driven out by thebeveled key P. The key P is attached to the end of the rod 0 at one end,while the other end of the said rod 0 is firmly fastened to the handleM. M is provided with the guide-plates h, which play over the handle M.The helical spring 0 is held in place on the sliding rod 0 by the ears w00 through the latter of which it is journaled. By a similar ear, no",it is kept in place.

The upper end of the rod 0 is rigidly attached to the ear as, which isfastened to the lower end of the handle M. The springs N N on theelevated platform are for the purpose of holding the disks or openframe-work, which receives one end of the barrel or keg, above the toolsin the tool-box. By pressing on the lever 0 when the machine is inoperation, the barrel or keg is gradually operated on by the tools inthe tool-box.

Having now described the main features of our invention, we will proceedto explain its mode of operation.

The lever O is elevated and fastened to the clamp R, which is fixed inthe ceiling overhead. The headless barrel or keg, which has been hoopedat either end, is then placed over the shaft M. The lower end is placedwithin the disk D, where it is finished. Having removed the lever G fromthe clamp R, the upper end is received within the disk D by allowing thedisk D to drop down over the head of the barrel. Then the foot is placedin the shoe F and moves the shaft E, which, by means of the beveledcog-wheels K and L, causes the shaft M to revolve. This carries thetool-box I, with its accompanying tools, around the edge of the barrel,thus evening, beveling, and chamfering its edge. The hand is placed onthe handle M, pressing it downward and holding it firmly in thatposition.

This causes the key P to press outwardly the crozing-tool c, which makesthe proper channel in the end of the barrel for receiving its head. Whenthe hand is removed from the handle the spring 0 raises the key P, andcauses the crozing-tool c to recede to its former position. The barrelis then reversed, and the same operation is performed on the other end.

Having now fully described our invention and its mode of operation, whatwe claim, and desire to secure by Letters Patent, is-

1. The platform B, the springs N N, and the shaft M, in combination withthe movable lever O, with its depending disk D, substantially asdescribed, and for the purposes set forth.

2. The handle M, provided with the guides h and the ear az, incombination with the sliding rod 0, the helical spring 0, the key P, theshaft M, and the tool-box I, substantially as described, and for thepurposes set forth.

3. The tool-box I, provided with the tools a b c d, the bridges g g, thesetscrew 0, and the spring f, in combination with the shaft M, thehandle M, the sliding rod 0, provided with the key P and the helicalspring 0, the disk D, and the springs N N, substantially as de scribed,and for the purposes set forth.

4. The platform B, the shaft E, provided with the shoe F, and thebeveled cog-wheel K, in combination with the shaft M, provided with thebeveled cog-wheel L, the disk D, the lever O, the uprights A A, the diskD, and the springs N N, substantially as described, and for the purposesset forth.

I11 testimony that we claim the foregoing we have hereunto set ourhands.
